UNITED STATES PATENT OFFICEo THEODOR BAGGESEN, OF STRASBURG, ALSACE,GERMANY.

PERMANENT WAY OF RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 342,164, dated MaylB.1886.

Application filed January 21, 1886. Serial No. 189,321.

To all whom it may concern:

Beit known that I, THEoDon BAGGEsEN, a citizen of the free town ofLubeck, Germany, residing at Strasburg, Alsace, Germany, have inventednew and useful Improvements in the Permanent Vay of Railways, (for whichI have obtained Letters Patent in Luxemburg, No. 597, bearing dateNovember 5, 1885,) of which the following is a specification.

This invention relates to an improved construction of transversesleepers for the permanent way of railways, composed of wood andast-iron combined.

Ordinary castiron, owing to its want of elasticity, cannot be employedfor the con struction of transverse railway-sleepers, as it will notstand packing; but by the annealing process now largely adopted forcastings a certain elasticity is imparted to the metal, which enables itto bc readily employed for the purpose, as the maximum strain to whichthe metal is subjected can be kept well within the elasticlimit,theexpense involved in rolling wrought-iron sleepers being available forincreasing the mass of the castiron sleepers.

My invention consists in the novel construe tion and combination ofdevices hereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure l shows a part side view, Fig. 2a plan, and Fig. 3 a cross-section of the sleeper and chair combinedtherewith.

Similarlettersindicate corresponding parts.

In the drawings, the letter A designates the cast-iron sleeper, and Bthe wood sleeper.

In order to allow of an increased width of gage at curves, die., thebolt-holes in the iron sleeper A are slotted to an extent correspondingto the possible variation in gage, while in the wood sleeper B the exactpositions required for the chair-bolts are determined by a templet, andare then bored to the exact size for the reception of the screw-boltsa,which then take a corresponding position in the slots of the castiron,and serve to tie the wood and iron sleeper and chair firmly together.Thus the wood sleeper serves,to fix the gage, and enables one and thesame iron sleeper to be used indifferently for a straight line or forcurves;

at the same time it affords a more or less elastic bed to the rail or'chair, rendering the motion of the carriages more pleasant than withsleepers entirely of metal.

Although l have described my invention as applied to double-headedrails, yet it may be equally adapted for use with hanged rails, a metalbeing in that ease introduced between the rail and the wood sleeper, andthe fixing bolts being provided with dogs to clip the rail.

I-Ieretofore railroad-ties and fastenings have been composed of achanneled iron tie, a bed* plate riveted to the bottom thereof andprovided with T-shaped slots, clamp-blocks engaging the flanged base ofthe rail, and bolts having T- heads engaging the slotsin the bedplateand passing inward through the clampblocks, the upper ends of the boltshaving screw-nuts, by which the rail is clamped to said bed-plate. Inanother instancearailway has comprised an under-recessed cast-iron tiehaving longitudinal key-seats provided with notched rail-bearings intheir walls, and 1ongitudinal keys arranged in said seats andinterlocked with the bases 01"' the rails to secure the latter to theties; and, again, a railway has comprised a metal tie having end seats,end wooden blocks, on which the bases of the rails rest, and to whichthey are secured to constitute yielding supports for the rails, andmovable blocks engaging the inner iianges of the rails, and secured byspikes passing through said blocks into the base of the tie. Suchdifferent constructions do not constitute my invention, and are notclaimed by me.

Vhat l claim as new,and desire to secure by Letters Patent, is

l. A transverse sleeper forV the permanent way of railways, composed ofa lower annealed cast-iron sleeper having slotted boltholes for thepurpose of enabling this part to be used indifferently for a straightline or for curves, and an upper wood sleeper having bolt-holes .boredto correspond to the required gage, said iron and wood parts beingconnected by the fixing screw-bolts of the rails, substantially asdescribed.

2. rEhe combination, with a railroad-rail, of a lower cast-irontransverse sleeper, A, having slotted bolt-holes, whereby it is adaptedindifferently for u straight line or for curves, au upper Wood sleeper,B, placed above said iron sleeper aud having bolt-holes bored tocorrespond to Jche required gege, and the bolts a a, passed through thebolbholes in said sleeper, substantially :is described,

In tesbimony whereof I have signed my name to this specification in thepresence of two subseribing Witnesses.

THEODOR BAGGESEN.
